HMC904LC5 v02.0511 GaAs MMIC I/Q DOWNCONVERTER 17 - 24 GHz Typical Applications Features The HMC904LC5 is ideal for: Conversion Gain: 12 dB Point-to-Point and Point-to-Multi-Point Radio Image Rejection: 30 dB Military Radar, EW & ELINT 2 LO to RF Isolation: 45 dB Satellite Communications Noise Figure: 3 dB Input IP3: 0 dBm 32 Lead 5x5mm SMT Package: 25mm Functional Diagram General Description The HMC904LC5 is a compact GaAs MMIC I/Q downconverter in a leadless RoHS compliant SMT package. This device provides a small signal conversion gain of 12 dB with a noise figure of 3 dB and 30 dB of image rejection across the frequency band. The HMC904LC5 utilizes an LNA followed by an image reject mixer which is driven by an active x2 multiplier. The image reject mixer eliminates the need for a filter following the LNA, and removes thermal noise at the image frequency. I and Q mixer outputs are provided and an external 90 hybrid is needed to select the required sideband. The HMC904LC5 is a much smaller alternative to hybrid style image reject mixer downconverter assemblies, and is compatible with surface mount manufacturing techniques. 1 Electrical Specifications, T = +25 C, IF = 1000 MHz, LO = +4 dBm, Vdd = 3.5 Vdc USB A Parameter Min.
